STMicroelectronics Unveils New Chip to Slay Vampire Power in Appliances, Lighting, and Industrial Equipment
(Thomson Reuters ONE) -
New off-line converter IC with class-leading zero-power standby introduces
unique smart management for convenient system wake-up
Geneva, October 27, 2015 - The reign of dreaded "vampire power" could be about
to end thanks to the latest power-supply chip from STMicroelectronics (NYSE:
STM), a global semiconductor leader serving customers across the spectrum of
electronics applications. The new IC meets the international specification for
zero standby power, and is the first in the world to provide a smart way of
managing the wake-up function in appliances such as white goods, in lighting,
and in industrial equipment.
The long-running battle to minimize power sucked in by equipment in standby mode
(vampire power) has driven worldwide adoption of proposals such as the IEA[1]
initiatives to reduce standby power used by appliances to less than 1W in 2010
and 0.5W in 2013. Today, the most advanced power-supply technologies are capable
of driving down standby power consumption below 5mW, which is rounded to zero
according to the IEC standard for household and office appliances.[2]
Although regulations are driving down standby power per appliance, the number of
appliances in use globally is increasing. ST's new VIPer0P IC helps reduce
wasted power and CO(2) emissions by enabling effective zero-power standby in
appliances such as clothes dryers, washing machines, dishwashers, coffee makers,
and microwaves. The chip can also be used in lighting controls, industrial
appliances, and air conditioners. By introducing a unique, patented smart-
management capability not offered by any other converter in the market, VIPer0P
allows the appliance to be woken from standby via a touchscreen or remote
control thereby enhancing convenience for users.
"Designers at the world's leading appliance brands rely on our VIPer(®)
avalanche- rugged integrated Power ICs to meet the toughest eco-design
specifications," said Matteo Lo Presti, Group Vice President, Industrial & Power
Conversion Division, STMicroelectronics. "VIPer0P now adds advanced zero-power
technology to the superior ease of design, energy efficiency, and ruggedness
that characterize the VIPer family."
VIPer0P has been designed into forthcoming new appliances by lead customers, and
is now in volume production in the SO16N surface-mount package, priced from
$0.54 for orders of 1000 pieces.
Further Technical Information:
Thanks to its unique smart architecture, VIPer0P is able to provide standby
power for the system host microcontroller while in idle mode. This allows the
system to be woken via the main-appliance user interface, such as the
touchscreen or a remote controller. There is no need for a dedicated high-
voltage mechanical switch to take the appliance out of standby. VIPer0P consumes
less than 5mW in idle mode (at 230Vac supply). This best-in-class performance is
rounded to zero power according to Clause 4.5 of the IEC 62301 standard for
household and office appliances.
If a switch is used to control standby, idle power can be further reduced to
4mW. Switching can be done at Safety Extra-Low Voltage (SELV), hence eliminating
bulky high-voltage components.
VIPer0P is an off-line power-converter IC that can be configured as a flyback,
buck, or buck-boost switched-mode power supply (SMPS). As the latest member of
ST's high-voltage VIPerPlus series, it integrates an avalanche-rugged Power
MOSFET with class-leading breakdown voltage of 800V thereby giving designers
greater safety margin to ensure superior reliability. VIPer0P also has
comprehensive protection features including short-circuit protection, Vcc
clamping, thermal shutdown, and soft-start. The oscillator controlling the
switching frequency is jittered to minimize electromagnetic interference.
Additional features include integrated high-voltage startup circuitry, error
amplifier with 1.2V reference and separate ground for direct feedback
connection, and a sense-FET for energy-efficient current sensing. These simplify
design and minimize external components thereby saving bill-of-materials costs
and board space. In addition, VIPer0P's self-supply design simplifies
transformer selection by eliminating any need for an auxiliary winding.
